What does Acts 15:41 mean?

Paul is on the road again. The church in Jerusalem has given him a letter explaining Gentiles do not need to follow the Mosaic law but should make some concessions to strengthen their unity with Jews in their churches (Acts 15:22–35). Barnabas and Mark will take the letter to Cyprus (Acts 13:4–12; 15:39). Paul and Silas will take the letter to churches that Paul and Barnabas planted in Modern-day Asia Minor: Pisidian Antioch, Iconium, and Lystra (Acts 13:13—14:23; 16:1–5).

Paul and Silas start by sharing the letter with the churches in the province of Syria outside of Antioch. This includes the district of Cilicia on the far east of the southern shore of modern-day Asia Minor; likely, they also visit Tarsus, Paul's hometown. From there, instead of sailing to Pamphylia, they trek over the steep pass to the province of Galatia.

While in Lystra, Paul will meet the son of his heart: Timothy. Although the apostles and elders in Jerusalem have made it clear that Gentile Christians do not need to be circumcised, Timothy's mother is Jewish. To ensure the young man avoids any trouble with Jews who would show him disrespect (1 Timothy 4:12), Paul circumcises him, then brings him along (Acts 16:1–3). From there, they will go on through Galatia (Acts 16:6), across to Macedonia, down into Greece, and back to Asia, the province on the western shore of Asia Minor (Acts 16:6—18:21).
